TAKE-UP IVIECHANISM FOR LOOIVIS.

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed February 23, 1905. Serial No. 246,827.

To (all wir/077e 1125 Uta/y concern/ Be it known that I, Geenen G-ooDLINn, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Take-Up Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a take-u p for use more especially in connection with looms for weaving' silk and delicate fabrics or the like. IIeretofore difficulty has been experienced in keeping the silk fabric stretched or smoothed and free from creases on its way to the take-up roller, and diderent appliances have been used in the nature of ribs, zc., that serve to smooth out or stretch the fabric from its median line toward the selvages. Usually, also, the fabric has been passed over a roller sustained on the breastbeam of the loom. I have found that I may smooth out and prevent wrinkles from being formed in the fabric and going onto the usual cloth-receiving` roller by drawing both sides of the fabric over a plurality of smooth stationary surfaces located' between the sand or take-up roll and the usual cloth -receiving roller. The stationary bars or rollers referred to may and will preferably becomposed of wood.

Figure I, in section on the line a', Fig. 2, shows a suflicient portion of a loom embodying myimprovements to enable my invention to be understood. Fig. 2 is a front end view of the loom shown in Fig. 1, the web-protector being broken out. Fig. 3 shows in two views a modified form of stationary bar or roll to illustrate another way of restraining the rotation of the bar or roll.

The loom-frame A, the crank-shaft A, sustained in suitable bearings on said frame, the lay-connecting rods A2, the lay A, pivoted at and having a beam A" and a reed, the takeup or sand roll a?, and the cloth-receivingl roller or device c are and may be all as usual. The breast-beam B, herein shown as composed of wood, is shaped at its outer side to present a curved surface.

The woven web a is led from the front of the breast-beam down under a revolving weightroller a', thence over and under a take-up or sand roll (t2 of larger diameter, the fabric or web on its way between the sand-roll and the cloth-receiving roller a being led over and across a plurality of stationary rolls or bars a a" ai', carried in levers (l, shown as of elbow shape, loosely pivoted on a rod d', held by setscrews Z2 on a frame d suitably bolted at Z to the framework, the short arms of said levers having connected with them springs (Z5, that act to draw the fabric about said sand-roll n? and take up any slack in the fabric. The rolls or bars shown present curved surfaces that contact with opposite sides of the fabric, and said rolls or bars are located quite close together, as thereby the fabric is better smoothedv or ironed and kept under a more even and uniform tension, and the liability of wrinkles due to uneven strain on the fabric is less than were the rolls or bars widely separated.

The roll a, the take-up or sand roll c2, and the cloth-receiving roller a6 are sustained in two side frames d, suitably secured at their lower ends tothe loom sides and at their upper ends to the under side of the breast-beam. One side frame has a stud L2, that receives over it loosely the hub 3 of a ratchet-wheel L", said hub havinga pinion bl. This ratchetwheel may be moved intermittingly by any means usual in looms for this purpose-as, for instance, a pawl 7), connected with a lever moved by the lay. The pinion If engages a toothed gear c, having a connected pinion c, that in turn engages a toothed gear c2, fast on one of the journals of the sand-roller a2. The opposite journal of said` roll has a sprocketwheel e, over whichis passed a sprocket-chain c, that in turn engages a sprocket-wheel e2 on one end of the cloth-receiving roller. The sprocket-wheel c is clamped securely in work; ing position on the liournal of the sand-roll ai by suitable nuts, and by loosening said nuts the wheel e may be disconnected from said roll, as when it is desired to draw the fabric off the cloth-receiving roller, at which time the roll must turn freely.

The bars or rolls a a* on will be restrained from rotation as the web is drawn over the same by any suitable means, the means shown in Fig. 1 being screws extended through the levers (Z and entering the ends of the bars snugly, thus restraining the rotation o'f said bars between said levers. If desired, however, each bar or roll may have a projection p at each end, said projection being other than round, and said projection may enter ways between lianges p, forming parts of the rolls, as shown in Fig. 3.

I have arranged a web-protector B' in front of the breast-beam, it serving to prevent the weaver from coming in contact with the woven web.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a loom, a breast-beam, a cloth-receiving roller and a sand or take-up roll to which the cloth being woven is led, combined with a plurality of stationary bars arranged be tween said sand or take-up roll and said clothreceiving roll and between and about which the woven cloth is drawn and ironed by the Contact of said cloth at both sides with said bars on its way to the cloth-receiving roller.

2. In a loom, a revolving take-up roller, a plurality of non-rotatable devices having arcshaped surfaces over which the fabric passes' prior to being wound on the take-up roll, a movable frame sustaining' said devices, and a yielding device acting to retain said frame in its operative position.

In a loom, a breast-beam, asand or takeup roller, a weight-roller acting on the cloth between said breastbeam and sand or take-up roller, a cloth-receiving roller and a movable Jrame sustained in front of said sand or takeup roller and provided with a plurality of stationary bars over which the cloth is led after it leaves the take-up or sand roller on its way to said cloth-receiving roller, said stationary bars acting' upon opposite sides oic the cloth and ironing and smoothing the cloth to remove any wrinkles therefrom as the cloth approaches the receiving-roll to be wound there- In testimony whereotl I have signed my name to this specification in the presence of two subscribing witnesses.
